CS5201-1GSTR3

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The CS5201-1GSTR3 is a 1.0 A adjustable linear regulator from onsemi, housed in an SOT-223 package with tape and reel shipping. It provides an output voltage range of 1.25 V to 5.5 V using two external resistors, maintaining accuracy within ±1.0% over temperature. The device operates with dropout voltages less than 1.2 V at full load and features fast transient response. Electrical characteristics include a reference voltage of 1.241 V to 1.266 V, line regulation of 0.20%, and ripple rejection of 80 dB at 120 Hz. Protection mechanisms include current limit and thermal shutdown.
